i have a 98 ek that was automatic now converted to manual. i put in a 99 gsr motor. at first i put in a si engine harness and si ecu ran but no speedo or tach and idled high and no low end. figured out that just doesn't work. so i put in stock ex auto harness with obd2 gsr ecu. now everything is fine BUT it will only rev up to 2 grand and it sounds kinda but it isn't a rev limiter. does not sound healthy at all. i just figured out i forgot the iab senor on the skunk2 mani. could it be bad resistence on a sodered wire,different pin-outs, other forgotten wire. im outta ideas and need help real bad. SOMEONE PLEASE HELP!!!!!!!

 

Try posting in the Hybrid section, they might also be able to help on swaps like these
